Today is National Punctuation Day – we know it’s official because there’s even a Web site dedicated to it – and what better way to celebrate than with a little Electric Company. LL’s guest spot on the reboot of the 1970s classic children’s show is a rapped explainer of the importance of punctuation. We highly suggest listening a few times while you make the official National Punctuation Day meatloaf. (Head over to nationalpunctuationday.com for the recipe.)
